HENRY O. SMITH, OF NEW YORK, N. Y.

CAR-WHEEL.

SPECIFICATION forming part of Letters Patent N o. 231,503, dated August 24, 1880.

Application led March 26, 1879.

To all whom tt may concern Be itknoWn that I, HENRY C. SMITH, of the city, county, and State of New York, have invented certain new and useful Improvements in Oar-Wheels, of which the following is a specification.

My invention relates to that class of wheels the object of which is to deaden the sound made by the wheels on the track and to relieve by their elasticity the jolting ofthe cars.

The invention consists in making the wheel in parts, and ot iron land other more elastic lnaterial, also in making the wheel of unusual Width, with the flan ge in its center, for the purpose hereinafter more fully set forth.

In the drawings, which are hereby made a part of this-specification, Figure l is asection through the center ot' the wheel, showing all its parts. Fig. 2 shows the inside of the anged part. Fig. 3 shows a circular disk, a part of the Wheel. Fig. 4t is a view of the elastic material, andFig. 5 a view of the tire.

To enable others to make and use my ilnproved wheel, I will describe it in detail.

The part B (shown in section in Fig. 1) is cast in one piece, forming the flange a, face M, hub N, on which the elastic part D is fitted, and shoulder b, onto which the circular disk O is tted. The inside surface ot' the part- B has projecting points to assist in holding the elastic material, as shown in Fig. 2.

The disk O, Fig. 3, is a circular plate having projecting points on its inside to assist in holding the elastic material, and tits on the shoulder b, as above stated.

The circular part D is made in the form shown in Figs. l and 4, fits onto the hub N,

Fig. 1, and is made of any elastic substance, as hard rubber, Wood, leather, or other suitable material. The parts B, C, and D have perforations, through which the bolts m pass to hold the parts together. The part B, Fig. l, has the metallic face M, on which the brake operates, to save the wearing ot the face of the elastic part D.

Oar-wheels constructed in parts in the nianner shown have two faces, M and D, and with the elastic part D running on the rail, make little noise and jolt the cars verylittle. When desired, the central elastic parts may be made a little smaller, and an iron or steel tire (shown in Fig. 5) may be put on the same, the wheels giving nearly as good results.

Having described my invention, what I claiin as new, and desire to secure by Letters Patent, is-

l. The car-wheel A, herein described, having two faces and consisting of the part B, provided with aange and having the projecting points shown on its inside, ofthe circular disk or part O, also having projecting' points on its inside, of the elastic part D, arranged and held between the before-mentioned parts, and of the bolts m, all the said parts constructed and combined as shown and set fort-h.

2. In a car-wheel, the combination, with the metal part B, having a brake-tread and a projecting guide-flange, of the non-resonant part D and an outer clamping-plate, substantially as described.
